Application filed February 23, 1912. Serial No. 679,229.

To all whom it may concern:

Be it known that I, NELSON J. RUSSELL, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and'uscful Improvements in Actuating Mechanism for Gas-Generating Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates particularly to gas generating machines adapted for use in generating gas from gasolene, and has for its object to improve the same in the several particulars hereinafter stated.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in front elevation showing the improved generating machine; Fig. 2 is a side elevation of the machine with some parts broken away and some parts sectioned; Fig. 3 is a view partly in front elevation and partly in vertical section showing the right hand portion of the machine; Fig. 41 is a detail in vertical section taken on the line at m on Fig. 3; Fig. 5 is an enlarged view on the same section as Fig. 4:; Fig; 6 is a section taken on the line co m on Fig. 5; and Fig. 7 is a section taken on the line a m on Fig. 3.

In the type of gas generating machines shown in the drawings, a rotary air supply and compressing drum 1 is arranged ,torotate within the water containing tank '2,

this being a type of air compressor well known in this artand heretofore frequently employed. For the purposes of this case,

it is only necessary to call attention to the fact that. in the complete generating app a.-

ratus, air is supplied to, the carburetor by rotation of thesaid drum 1. The water tank 2 of this air compressor or air pump is, as shown, supported by a suitable framework made up of front and rear members 3 and 4, and end members 5 and 6. Said frame membersat the corners of the'frame structure are rigidly but detachably connected, preferably by suitable bolts 7 which permit the sections of the frame-work to bereadily disconnected for the purpose of shipment or storage. As a convenient means for supporting the tank 2 on the framework, the front and rear members 3 and 1 are shown as provided with rest lugs 8 that engage the outwardly projecting flanges of reinforcing angles 9 riveted to the upper edge of the said tank 2. The rotary air supplying drum 1 is provided with a shaft 10, journaled in suitable bearings on the ends of the drum 2, and at one end, projecting and journaled also in the right hand end framemember 6. This projecting'end of the said drum shaft 10 is provided with a relatively large sprocket 11 and a relatively small sprocket 12.

Journaled in the end frame members 6 and in the transverse tie bar 13 of the framework is a counter shaft 1 1 on which is a Windlass drum 15 that is preferably keyed to said shaft. At its left hand end (see Figs. 3 and 7), the Windlass drum 15 is provided with a ratchet wheel 16, and at its right hand end, said drum is provided with one or more laterally projecting ratchet teeth 17. Loosely journaled on the shaft, 141 adjacent to the ratchet wheel 16 is a large sprocket 18 provided with a spring-pressed dog 19 that cooperates with thesaid ratchet wheel 16. Loosely journaled on the right hand end of the counter shaft 14 is another sprocket 20 and laterally projected ratchet tooth 21 adapted to be engaged with the ratchet tooth 17 of the drum and to be disengaged therefrom, by lateral sliding movements of the said sprocket 20., The said sprocket 20 is shown The numeral 23 indicates a mast or column, preferably in the form of a metal pipe,

which is detachably connected to the framework, being preferably passed through an upper guide lug 2a, and with its lower end seatedin a pocket 25, both of which elements 23 and 24: are shown as cast integral with the rear frame member 4. A sheave supporting head'26 is supported by themast 23 being, as shown, provided with an inand 18.

verted pocket in which the upper end of the said mast is inserted. Guide sheaves 27 are journaled-to the ends of the head 26. y The numeral 28 indlcates an operating cable which is passed over the guide sheaves 27, is provided at one end withaheavyweightv 29,'and at .its other end is Wound upon and securedt'o thewindlass drum 15.

The numeral 30 indicates a sprocket chain which runs over The numeral 31 indicates a spur gear which is journaledfon a trunnion 32 projectingfrom the upper portion of the right hand frame 'sectione." Thegear31 carries a small sprocket i33yover which and a large laterally movable sprocket 20 on the shaft 1 1-, a. sprocket chain 34 is arrangedto run.

The numeral 35 indicates an operating crank, the shaft of which is journaled in the upper portion of the frame section 6 and is provided with a spur pinion 36 that meshes with the gear 31. or r I With the above described construction, it is obvious that when'the weight 29 is raised,

it will. exert a force which acts through the. cable 28, drum 15, ratchet wheel 16, dog 19,

sprockets 12 and 18, and chain 30,1willrotate the air supplying or compressing drum 1 in the directionof the arrow marked adjacent to said drum on Fig. 2. Also,,no-rmally, the ratchet tooth 17 of-. the"clru1n;15 is free from the ratchet tooth 21 of the sprocket :20, so that the said sprocket20, chain 34, sprocket 33,

tion stated, to supply air'for the generation of gas. When the weight 29 is to be wound up, the sprocket 20 is moved laterally so that its ratchet tooth .21 will engage the ratchet tooth 17 of the Windlass drum, and then by rotation of the operating crank 35,

the said drum may be rotatedbackwardor in a direction to wind up thereon, the cable 28 and thereby raise the weight 29. This winding of the weight thus rotatesthe, drum 1.5 backward without rotatingthe air supplying. drum 1,,f0r.the reason thatv the ratchet wheel; 16, under backward-rotation,

will pass freely under the dog .19 of, the sprocket 18. Thusit'will be seen that the weight, may be raised very quickly and easily at anytime without interrupting for more thana few moments the air supplying action ofthe compressor pump. 1..

In gasgenerating apparatus ofthis char- I acter, it is a common practice to supply the gasoleneas well as air tothe.;carbureter chamber or-device-by -means of a pump. For this purpose I preferably employ a cylinder and piston pump of the character disclosed and claimed in my p di g rp cation, S. N. 660,915, filed of date, Novem- 7 her 17th, 1911,'and entitled, Pump. My

the alined sprockets 7 gears l and 36, and, crank stand idlefwhile thejsaid-air supplying drum is being rotated in the 'direcv character;

invention also includes novel. connections whereby the piston of this pump will be reciprocated under a -minimum of friction from power supplied by the Weight utilized to drive the drum of the air compressor. Of

the parts of this gasolene pump, the numeral 317 indicates a cylinder structure which, as shown, is suitably secured to the frame section 6, andthe numeral 38 indicates the rod of the said pump piston. The upper end of the piston rod 38 is connected by a link 39 to n the freeend of an arm 40, pivoted at 4:1 to

the said frame section 6. In its free. end, 7

the arm 410-is provided with alongitudinal slot 42 in which works the crankpin 43 of the crank disk 1a. The crank disk. 44 and a sprocket 4.5 areboth,,as shown, secured to a short shaft A16 journaledin the upper portion of the frame section 6 (see Fig. 6). A

sprocket chain 47 runs over the sprocket and over the sprocket 11, ,heretoforenoted, as located on the shaft 10fof the air supplyin'g drum l. By reference to Fig. 5, it will with. a spirally spaced serieslof perforations 48, into any one of wliicllthe crank pin43 may be inserted to thereby afford a vertical throw crank adapted to be adjusted so asto give just the desired amount of gasolene per 95 unit of air supplied by the rotarydrum 1. The, adjustment of the saidcrank, therefore, determines the percentage orrelative amount ofoil-and air that will be mixed to produce the gas, and when thispercentage or proportion isdetermined by the setting of the crank-pin, that certain per cent. or proportion will be'maintained, j regardless of whether or not thegas. is used slowly orrapidly. i Otherwise stated, one rotation of the 5 air supplying drum 1 will supply a prede termined amount of air. and will cause a predetermined number of movements of the piston of the gasolen'e supplying pump and,

consequently, the predeterminedamount of gasolene for mixture with air. I 7

By referring to Fig. 4, it will be noted that the pivotal connection betWeen-thelink 3 9 and the arm 40 moves approximately on a vertical line coincident with the projected '3 axis ofi'thepiston rod Otherwisestated, the said link 39 moves without any perceptible angularity or-deviation-from aline 'ment with the piston rodr Hence, in some practicable; to

instances, it may be found connectithe piston rod directly to the free end ofthe said arm 40."

The pump driving mechanism above 7 described, is simple, generally efficient and be noted that thecrank disk '44 is provided 7 highly desirable fojr us'ein GOIlneCtlOIl ;Wlth

a gas generating machine of'this general The machine 'is'adapted'to be easily taken apart and packed in asmallspace for shipment; Asalready indicated, the sections of the framework may beeasily separated and the head 26 may be easily detached from the mast 23 and the said mast easily detached from the said frame. At the same time the machine, when the parts are set up, constitutes a self contained structure adapted to be moved as an entirety, without changing any of the adjustments or relative positions of the parts of the machine. Attention is further called to the fact that when the weight 29 is being wound up or raised, the oil or gasolene supplying pump as well as the air supplying pump or compressor remain idle.

What I claim is 1-- 1.. A motor for gas generating machines and the like, provided with a motor driven element, comprising a projecting shaft on said motor driven element, a counter-shaft, a Windlass drum on said counter-shaft, a sprocket on said counter-shaft adjacent one end of said Windlass drum, a sprocket on said projecting shafit, a sprocket chain running over said sprockets, a pawl and ratchet connection between said Windlass drum and the adjacent sprocket, a weight, a cable connecting said weight to said Windlass drum, a crank driven sprocket on the machine frame, a laterally movable sprocket located on said counter-shaft adjacent the other end of said Windlass drum, and a sprocket chain running over the latter noted sprockets, the said laterally movable sprocket and the said Windlass drum having cooperating lugs en- Gopies of this patent may be gageable by lateral movements of the said sprocket, substantially as described.

2. A motor for gas generating machines and the like provided with a motor driven element, comprising a projecting shaft on said motor driven element, a counter-shaft, a Windlass drum on said counter-shaft, a sprocket on said counter-shaft adjacent one end of said Windlass drum, a smaller sprocket on Said projecting shaft, a sprocket chain cooperating with said sprockets, a pawl and ratchet connection between said Windlass drum and the adjacent sprocket, a weight, a cable connecting said weight to said Windlass drum, a relatively small driving sprocket on the machine frame, a relatively large gear fixed to said sprocket, a crank driven pinion meshing therewith to drive said gear, a lat erally movable and larger sprocket located on said counter-shaft adjacent the other end of said Windlass drum, and a sprocket chain cooperating with said driving sprocket and said laterally movable sprocket, the said laterally movable sprocket and the said windlass drum having cooperating lugs engageable by I lateral movements of the said sprocket, substantially as described.
